Fretting Wear Mechanism of Plasma Sprayed WC/18Co Coating
英文摘要
The fretting wear mechanism of plasma sprayed WC/18Co coating has been investigated by OM,SEM,EPMA,XRD and profilometer.It was shown that the fretting wear of plasma sprayed WC/18Co coating was mainly adhesive at initial stage,and its fretting wear resistance was higher than that of 1Cr18Ni9Ti stainless steel on account of its high hardness.But at steady stage,the wear mechanism tended to be of surface delamination and fragmentation owing to its brittleness and low adhesive strength.The main factors affecting fretting wear resistance were porosity and oxide inclusions in WC/18Co coating.
